The heart of the Teledyne Laars Mighty Therm is
its integral finned copper heat exchanger, having nine times the surface
area for heat transfer as a smooth tube of equal length.

The low water volume design practically eliminates
standby losses, and the Mighty Therm operates at temperatures as low as
41 Deg C. without condensation.

Teledyne Laars Mighty Therm is engineered to provide
maximum efficiencies up to 82% for hydronic heating, domestic water and
industrial process heating. Each type is available in a broad range of
sizes with a wide selection of precise controls designed to meet various
applications.

Sizes range from 51.3 Kw to 1465 Kw. A choice of
on/off firing, multi-stage firing, continuous fuel modulation and multi-boiler
operation combines with options and accessories to meet all special code
and insurance requirements.

Quiet efficient and space saving, Teledyne Laars
Mighty Therm is designed for many years of reliable and economical use.

Volume Water Applications

Model VW - Volume Water Heater

Volume Water Heater is completely assembled at
the factory and simple to install. Sizes 51.3 to 117.2kw can be ordered
either indoor or outdoor and are used in conjunction with storage wherever
a large volume of hot water is required, such as apartments/condominiums,
hotels, schools, hospitals and laundries.

Model PW - Volume Water Heater with Pump

The addition of a factory mounted and matched
pump provides installation and operation advantages of a packaged system.
Pumps are sized for pressure drop through the heat exchanger plus 9.1 M
of full sized pipe equal to flange connections and normal fittings. Available
in inputs from 51.3 to 534.7 Kw for indoor or outdoor applications.

Model IW - Instantaneous Volume Hot Water

Designed to deliver hot water using building piping
instead of a storage tank. Suitable for applications with load diversity
such as apartments/condominiums and motels. Available in indoor and outdoor
models sized from 146.5 to 534.7 Kw input.

Hydronic Heating Applications

Model HH - Hydronic Boiler

This is a reliable, high efficiency space heating
boiler with a wide range of control options. It is completely assembled
at the factory and easy to install. The Teledyne Laars copper finned tube
concept is at the heart of the Model HH. The high efficiency heat exchanger,
together with long life stainless steel burners and control options, provide
fast response, load matching and energy conservation for the best approach
to space or process heating. Available in inputs from 51.3 to 1465 Kw,
the mighty Therm can be installed as an individual boiler or in multiple
units.

Model PH - Hydronic Boiler with Pump

This model embodies all the features of the Model
HH plus a factory mounted and matched boiler circulating pump. This model
is intended for use in "primary-secondary" systems, which utilize a primary
pump to circulate heated water through the system and a separate pump to
circulate water through the boiler. The model PH provides package convenience
for primary-secondary design, variable flow, multiple boiler and low temperature
applications. Available with inputs from 51.3 to 534.7 Kw.

MIGHTY THERM FEATURES - All models

Greater energy efficiency as high as 82% are achieved
through state-of-the-art design. Efficient heat transfer and reduced standby
losses result in lower operating costs. Mighty Therms energy efficiency
has been tested by both AGA Laboratories and the Canadian Gas Association.

Design-certified by American Gas Association Laboratories
under ANSI Standard Z21.13, and Canadian Gas Association standards. Boilers
may be specified for use with natural or propane gas.

Indoor and outdoor models are available for maximum
application flexibility.

Working pressure of 160 psi is standard in accordance
with Section IV ASME boiler and Pressure vessel code. Units are factory
tested at 400 psi and registered with the National Board of Boiler and
Pressure Vessel Inspectors or the applicable Canadian provincial jurisdiction.

Heat exchanger headers conform to Article 2, part
HC of ASME Code. External head covers are field removable for complete
inspection of tubing and header passages. Heat exchanger is replaceable
without disassembly of burners or combustion chamber.

Pressure relief valve is ASME rated and is selected
to provide discharge capacity in excess of unit heat input.

The warranty provides complete protection : one
year on materials and workmanship for controls, combustion chamber, pump
and tank (if provided); five year warranty on heat exchanger tubes (warranted
against thermal shock for the life of the boiler); and five years on all
other parts.
